Answer:
![\frac{4}7](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D7)
Step-by-step explanation:
Just as a reminder, to find the ratio of 2 numbers, you divide the first by the second, and to divide 2 fractions, you multiply the dividend by the reciprocal of the divisor.
In this case, that would be:
![\frac{\frac{4}{5}}{\frac{7}{5}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B4%7D%7B5%7D%7D%7B%5Cfrac%7B7%7D%7B5%7D%7D)
![= \frac{4}{5} \cdot\frac{5}{7}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B4%7D%7B5%7D%20%5Ccdot%5Cfrac%7B5%7D%7B7%7D)
=![\frac{4}7](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D7)
I hope this helped you.
Answer:
No
Step-by-step explanation:
A matched pair design is used when we have two different observation about a certain experiment for each subject such that there is a natural pairing between the two population.
In the scenario described above, we have 20 subjects of which 10 are boys and 10 are girls.
Matching boys and girls having similar numbers does not depict natural pairing and thus using a matched paired test would be inappropriate. The test to use for such experiment is the two population t test.
